How do you control the stacking order of ::before and ::after pseudo-elements?

Q: How do you control the stacking order of ::before and ::after pseudo-elements?

The stacking order of `::before` and `::after` pseudo-elements is controlled using CSS `z-index` in combination with the `position` property. By default, `::before` is rendered behind the content of the element, and `::after` is rendered in front. You can change this behavior by specifying `z-index` values. Pseudo-elements participate in the CSS stacking context like regular child elements. To use `z-index`, the pseudo-element must have `position` set to `relative`, `absolute`, or `fixed`. Higher `z-index` values appear above lower ones within the same stacking context. Default order without `z-index`: `::before` behind content, element content in the middle, `::after` on top. .box { position: relative; width: 150px; height: 100px; background-color: lightgray; margin: 20px; } .box::before { content: ''; position: absolute; top: 10px; left: 10px; width: 50px; height: 50px; background-color: red; z-index: 1; } .box::after { content: ''; position: absolute; top: 20px; left: 20px; width: 50px; height: 50px; background-color: blue; z-index: 2; } In this example, the blue `::after` pseudo-element appears above the red `::before` pseudo-element because it has a higher `z-index`. Adjusting `z-index` lets you layer pseudo-elements relative to the element's content and each other. Always set `position` before applying `z-index` to pseudo-elements. Use `z-index` to control visual stacking, especially for decorative overlays or layered effects. Be mindful of stacking contexts created by parent elements, as they affect how `z-index` values interact. Test across browsers to ensure consistent rendering of layered pseudo-elements.
